Abstract

The reaction of [3 + 2] cycloaddition of a lappaconitine-based nitrone with N,N-diethylallylamine is accompanied by the formation of two minor products, unusual for the reaction of this type, containing the pyrrole cycle. The structures of the products have been established from the data of ¹H and ¹³C NMR spectra. The mechanism of their formation is proposed.
